Travellers who have been in the Democratic Republic of the Congo face a hard block on flights to the United States, under DRC Ebola travel restrictions that the US Centers for Disease Control and Prevention says are in force while the country fights what it now calls the second-largest Ebola outbreak on record. The restriction applies to everyone, US citizens included, who has been in DRC within 21 days of departure.

The restriction in plain terms
CDC’s current situation summary, last reviewed on 11 September 2026, states that US entry for travellers recently in DRC is temporarily restricted. Travellers who have been in the country within 21 days of their flight will not be allowed to board commercial flights with US destinations.
Three details matter for anyone planning a route. First, the bar covers US citizens and US nationals, not only foreign passport holders. Second, it captures transit: passengers with an intermediate stop in DRC, or on multi-stop itineraries routed through DRC, are covered whether or not they disembark. Third, the 21-day clock is a waiting period, not a formality — CDC tells US citizens and nationals to plan on remaining outside DRC for 21 days before entering the United States.
A softer rule applies to the neighbouring outbreak zone. US citizens and nationals who were in Uganda or South Sudan, and not in DRC, within 21 days of arrival must enter through designated airports for enhanced screening rather than any port of entry. All of this sits on top of a standing CDC order under 42 CFR 71.40, which continued temporary entry restrictions for certain categories of traveller present in DRC, Uganda or South Sudan.
How large the outbreak has become
The outbreak is caused by Bundibugyo virus, one of the orthoebolaviruses, and is DRC’s seventeenth Ebola outbreak. CDC says it is spreading substantially faster than previous ones and is now the second largest on record.
The speed comparison is the striking part. CDC notes the outbreak passed 1,000 confirmed cases within 40 days of response activation. The 2018 outbreak in DRC took roughly 235 days to reach the same mark. Confirmed cases have been recorded in Haut-Uele, Ituri, North Kivu, South Kivu, South Ubangi and Tshopo provinces, with South Kivu reporting no confirmed case since 29 May.
Uganda reported cases at the same time DRC declared its outbreak — 21 confirmed and probable cases and three deaths, with the last confirmed on 21 June. Cases linked to the DRC outbreak have also been reported in Kampala.
CDC has about 500 staff working on the response, including more than 120 deployed to the affected countries. The European Centre for Disease Prevention and Control is running its own assessment for European travellers and health systems.
Where CDC says not to go
CDC’s travel health notices split DRC into tiers. Ituri and North Kivu provinces sit at Level 4, avoid all travel. Haut-Uele and Tshopo sit at Level 3, reconsider non-essential travel. The rest of DRC and Uganda sit at Level 2, practise enhanced precautions — which in CDC’s framing means avoiding exposure and monitoring for symptoms while travelling and for 21 days after leaving.
For travellers, the practical read is that the notice tier and the boarding restriction are separate instruments. A Level 2 notice does not soften the 21-day flight bar, because the bar keys off presence in the country, not the province visited.
Why this one is harder to contain
CDC lists the constraints bluntly. Health infrastructure in the affected areas is limited, including access to diagnostics, laboratory services and infection prevention supplies. Ongoing conflict creates security problems and complicates contact tracing. Health workers are being infected while treating patients, with violence against them and shortages of protective equipment both cited. Frequent population movement across borders raises the risk of spread to Uganda, South Sudan and Rwanda. And mistrust of government, compounded by misinformation, makes public health communication harder.
Those are the same pressures that have shaped regional mobility policy elsewhere this year. Our reporting on China’s revised exit and entry regulations and on Australia’s shifting visa processing priorities shows how quickly health and security considerations move into ordinary immigration rules.
The decisions to watch
Three things will determine how long the boarding restriction stands. The first is case trajectory: CDC’s own comparison with 2018 suggests the response is measured against how fast the curve flattens, not the absolute count. The second is the standing order under 42 CFR 71.40, which has been extended in 30-day increments and is the legal instrument that would need to lapse. The third is whether Uganda’s run of no new confirmed cases since June holds, since cross-border spread is the pathway CDC flags most often.
Travellers with fixed dates should assume the rule stands until CDC says otherwise, and build the 21 days into itineraries rather than hoping for a waiver. Airlines enforce the boarding bar at check-in, so there is no practical appeal at the gate.
Reader questions
Who exactly is barred from flying to the United States?
Anyone who has been in the Democratic Republic of the Congo within 21 days of their flight, including US citizens and US nationals, cannot board a commercial flight bound for the United States.
Does a connection through Kinshasa count?
Yes. CDC says the restriction applies to passengers with an intermediate stop in DRC or on multi-stop itineraries via DRC, whether or not they leave the aircraft.
What about travellers coming from Uganda or South Sudan?
US citizens and nationals who were in Uganda or South Sudan, but not in DRC, in the previous 21 days are not barred from flying but must arrive through designated airports for enhanced screening.
How long must travellers wait before flying to the US?
CDC advises planning to remain outside DRC for 21 days before entering the United States, which matches the maximum incubation period for Ebola disease.
Which parts of DRC carry the highest travel notice?
Ituri and North Kivu provinces carry a Level 4 notice advising against all travel. Haut-Uele and Tshopo carry a Level 3 notice advising against non-essential travel.
Has the outbreak reached the United States?
No. CDC says no cases associated with this outbreak have been confirmed in the United States and rates the likelihood of spread there as very low.
